Zipp 303 XPLR SW Tubeless Disc Brake Front Wheel

Zipp 303 XPLR SW – for maximum speed on gravel

Zipp 303 XPLR SW Tubeless Disc Brake – a high-performance carbon front wheel designed for fast gravel riding and racing. The extra-wide rim profile is optimized for wide gravel tires, allowing lower tire pressures and helping to reduce vibrations caused by rough surfaces.

The 303 XPLR SW is designed around Zipp's Total System Efficiency (TSE) concept, adapted for gravel riding. The 32 mm internal width and 54 mm deep rim profile creates a smooth transition between the rim and a wide gravel tire, helping to reduce aerodynamic and rolling resistance.

The wheel uses a Hookless / Tubeless Straight Side (TSS) construction and is compatible only with Zipp-approved 40–61c TLR tires. Tires can be used with sealant or an inner tube. The maximum permitted tire pressure is 3.45 bar / 50 psi.

The front version uses a ZR1 Disc Brake hub, designed for durability and protection against dirt. The wheel is equipped with lightweight Sapim CX-Ray spokes, while the brake rotor uses the Center Lock mounting standard. The wheel is designed for a 12x100 mm front axle.
